INDIRECT SEARCHES FOR LEPTOQUARKS AT PRESENT AND FUTURE COLLIDERS

Abstract
We explore the sensitivities of e+e colliders (LEP, CLIC) and hadron-hadron colliders (CERN , FNAL , LHC pp and SSC pp) to the indirect effects of virtual scalar particles with superstring-inspired leptoquark and diquark couplings. We find that e+e colliders have better sensitivities via total cross section measurements of than via asymmetry measurements, and that LEP 2 is much more sensitive than LEP 1. Hadron-hadron colliders are sensitive via lepton-pair production cross sections ( μ+μ, τ+τ).
